I'm unsure how to even start this problem or how I'm suppose to find out the distance at which destructive interference would occur... Two loudspeakers are 1.8 m apart. A person stands 3.0 m from one speaker and 3.5 m from the other. (a) What is the lowest

Calculate the force of gravity on a spacecraft 12,800 km (2 earth radii) aboce the Earth\'s surface if its mass is 1400 kg. Ok for this question I first converted to meters for the radius then applied newtons law net force radial = m1 a radial = Fg = r^-2

4. ## AP Physics B

can you check my reasoning 1. The problem statement, all variables and given/known data ok well then... we did a lab were you have a hanging mass attached to a stirng that went through a straw and was attached to a rubber stopper. The lab was to find the

mass m1 was a robber stooper m1 was attached to a string that went through a straw on the other end of the straw the string came out and was attached to a mass m2 students spun mass m1 with hand on straw as the stopper spun around mass m2 the hanging mass

I did this net force = (m1 + m2) (radial acceleration of mass m1) = force of gravity on mass m2

why would the hanging mass of a radial acceleration if it\'s just in equilibrium...??? m1 V^2/r = m2 g

but i thought you were suppose to treat the Earth as the a whole object or something... my book said to think of it as one particle because everything is attracte4d to it no just the center of the plannet like even a person standing on the earth\'s surface
